Title: Improvements relating to the supply of feed water to steam boilers
IPC: F22D1/28
Filed: 1944-03-04
Abstract: 575,204. Steam boilers. FOSTER WHEELER, Ltd., SAMPSON, W., and HAYDEN, R. L. J. March 4, 1944, No. 4076. [Class 123 (ii)] Feed-water is supplied to the steam and water drum of a boiler by discharging it from a perforated pipe 1 in the form of upwardlydirected jets into a steam zone which is partly screened from the main steam space of the drum by wall 4 attached to the said pipe 1 at one side of the perforations thereof, the pipe 1 preferably being disposed longitudinally at about the normal water level in the drum. As shown, the wall 4 is hooded to form a roof 5 against which the water impinges before falling into a trough, constituted by two plates 6, 7 disposed on the pipe 1 on the side of the perforations opposite to the wall 4, from which it overflows into the boiler drum proper. The lower edge 10 of the plate 7 is spaced from the pipe 1 and, moreover, both the trough 6, 7 and the space between the plate 7 and wall 4 are subdivided by transverse partitions, not shown, so that, if and when the feed check valve closes, the pipe 1 will become and remain flooded.

Title: Improved feeler for examination or treatment of solid bodies by means of pressure waves
IPC: G10K11/02
Filed: 1949-02-16
Abstract: 663,280. Supersonic inspection devices. ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI. Feb. 16, 1949. [March 11, 1948] No. 4211/49. Class 118 (ii). [Also in Group XXXIX] Relates to means for coupling an electromechanical transmitting or receiving transducer, e.g. a piezo-electric crystal, to the surface of a solid undergoing test or treatment by pressure waves of the type disclosed in Specification 613,239 in which the transmitting or receiving surface of the transducer is in contact with an enclosed body of liquid under pressure, a portion of the fluid-containing wall comprising a flexibile elastic membrane, e.g. sheet rubber, which assumes the shape of the surface when brought into contact therewith. The liquid must be a good conductor of pressure waves and the contact with the surface is improved if the membrane is permeable by the liquid so that a liquid film forms on the outside of the membrane; means may be provided for automatically replenishing the loss of fluid. According to the present invention the wave-conducting fluid, e.g. water, is enclosed in a hollow tapered member, the transducer being mounted at the base of the member and the top end of the member being closed by the flexible wall. As shown a piezo-electric crystal 3 is supported by an insulating cup member 2 mounted in a recess in a conductive base 1. The crystal is centered by an insulating washer 4 and-is held by a conductive washer 5 locked by an externally threaded washer 6 which screws into the recess. The space between the rear surface of the crystal and the cup 2 constitutes an air gap and the rear surface of the crystal is electrically connected to the inner conductor 8 of a coaxial cable by means of a leaf spring 7, the front surface of the crystal being electrically connected to the outer conductor of the cable via the washers 5 and 6 and base 1. The tapered member comprises a hollow truncated cone 10 screwed onto the base 1 and the top of the cone is closed by a rubber membrane 12 clamped by an outer conical member 13 which screws over the inner cone. The membrane 12 is provided with an exterior nipple 15 which is intended to bear against the surface of the body under test. In order to provide access to obstructed areas of the surface, the tapered member may be curved.

Title: Hydraulic control system
IPC: F15B11/04
Filed: 1973-01-29
Abstract: 1410422 Programme control SANDERS ASSOCIATES Inc 29 Jan 1973 [13 March 1972] 4469/73 Heading F2V [Also in Division G3] A die-casting machine 21, Fig. 1, is operated by a ram 22 controlled first by a valve 25 to have the velocity characteristic shown at 44 in Fig. 2 and then by a valve 26 to produce the pressure characteristic 48, control being transferred to the valve 26 when the ram has reached a predetermined point in its travel to operate a switch in a bank 24 and the pressure in the ram has reached a predetermined value 45. An electronic signal source 32 capable of generating and repeating a wide variety of output signals energizes a force motor 31, Fig. 4, controlling a pilot valve 88 through a flapper valve 85, the signal from the pilot being applied through a conduit 58 to the right hand end of a spool 53 in the valve 25, Fig. 3. The spool is displaced until the pilot pressure is exactly opposed by a spring 56 and source pressure P acting against the left hand end of the spool which is now in a position to provide the required rate of flow through conduits 27, 28. When control is to be transferred to the valve 26, a solenoid 145, Fig. 6, energized by a ram-actuated switch in the bank 24 lifts a valve 136 to connect the space below a valve spool 109 to a return line 124 so that the spool may be depressed when pressure in the conduit 27 is great enough to compress a spring 118. The movement of the spool connects a space 61 to a pressure source Pc through passages 62, 65 so that a part 59b of the spool 53 is moved relatively to the remainder of the spool against a spring 67 to close the connections between the flow control valve 25 and the ram. Simultaneously, a switch 115 de-energizes the motor 31, energizes a signal source 34, similar to the source 32, for a force motor 33 in the pressure control valve 26 and starts a programme timer 37. The motor 33 displaces a flapper 93 against a piston 102 subjected to the pressure in the conduit 27 until an equilibrium position is reached. A fluid actuated spool 94 controlled by the flapper connects the conduit 27 with pressure and return lines Pc and R by the amount required to provide the required pressure in the ram. This pressure is eventually relieved by the timer de-energizing the force motor 33 and allowing the spool 94 to connect the conduit 27 only with the return line R. The fall in pressure in conduit 27 allows the spool 109 to be returned by the spring 118 to the position in which passage 65 is again connected with the return line 124 so that the parts of the spool 53 return to the positions shown in Fig. 3. Further signals from the timer energize the motor 31 to cause fluid to enter the ram at a slow rate and eject the die, and after this movement has been arrested by a switch in the bank 24, to reverse the ram.

Abstract: Sludges or suspensions in water of coal, clay or zinc or iron ore are separated therefrom as flocculent precipitated by adding an amphoteric colloid such as glue, caseine or starch in combination with either salts of trivalent metals such as aluminium sulphate or ferric chloride or with an acid or with both the colloid and acid or with calcium hydroxide or other alkali, the former being added before the colloid and the latter (alkali) thereafter, the time between the additions being as short as possible so as to obtain a homogeneous mixture before the last addition pulverized alkali may be added just before the colloid to become effective just after the addition thereof.  Aluminium sulphate is preferably added less than a minute before the colloid.  The sludge may be haematitic ore and the colloid be bone or other protein glue.  The colloid is added as a 1 per cent solution which has been allowed to mature for at least 10 hours. In examples quoted, some using 6 gms. of glue per m.3 and aluminium sulphate or ferric chloride solution containing 20 gms. thereof per m.3 added immediately before the glue, showed that turbidity was reduced to 0.05 and 0.1 respectively in 5 minutes and to 0.0 and 0.05 in 30 minutes.ALSO:Sludges or suspensions in water of coal, clay or zinc or iron ore are separated therefrom as flocculent precipitated by adding an amphoteric colloid such as glue, caseine or starch in combination with either salts of trivalent metals such as aluminium sulphate or ferric chloride or with an acid or with both the colloid and acid or with calcium hydroxide or other alkali, the former being added before the colloid and the latter (alkali) thereafter, the time between the additions being as short as possible so as to obtain a homogeneous mixture before the last addition; pulverized alkali may be added just before the colloid to become effective just after the addition thereof.
